The whole-cabin vibration absorbing device without the resonance peak comprises a bearing mechanism and a vibration absorbing mechanism; the bearing mechanism is fixedly connected with a tank plating bracket through at least one vibration absorbing mechanism so that the vibration amplification multiple within a concerned frequency band range of 5-2000 Hz is not more than 1; a heating element is mounted outside the bearing mechanism; a temperature homogenized heat tube is mounted in the bearing mechanism;at least one heat tube is placed in the bearing mechanism so that temperature differences of different positions of the bearing mechanism are less than 5 degrees centigrade; the vibration absorbing mechanism comprises a shell and an internal vibration absorbing element; the mounting direction of the vibration absorbing element is consistent with a direction in which the vibration is to be absorbed; and high frequency overall mean square root acceleration of a characteristic point on the bearing mechanism is not more than 10 grms. According to the whole-cabin vibration absorbing device withoutthe resonance peak, the highlighted vibration amplification multiple within the concerned frequency band range of 5-2000 Hz is not more than 1, the whole-cabin vibration absorbing device without theresonance peak is conducive to realizing whole-cabin vibration absorbing of a cabin section layer, improving the comfort of a single machine mechanical environment and reducing the types, number and weights of single machine vibration absorbers.
